The “oh!” exhibition, conducted as a long-term project by Saltcake, is a very special fun, enjoyable, and exciting play space for people tired of everyday life. It is designed as a special memory space where visitors can momentarily return to the innocent days of childhood and relieve stress, filling childhood memories anew with joy. This interactive exhibition was organized by Saltcake Media Lab’s task force, MisKorea (Media Interactive Story of Korea), under the company’s slogan of delivering the fundamental value of a happy experience.
